With 30-odd movies already under her belt and a no-BS approach to fame and life in general, it’s hard to believe Chloe Grace Moretz has only just turned 19!

In her latest movie Bad Neighbours 2: Sorority Rising, the actress plays college bad gal Shelby, who is basically the female equivalent of Zac Efron’s Teddy Sanders in the first film.

When she realises Madison (Selena Gomez), the goody-two-shoes leader of Phi Lambda Phi won’t allow any house parties, Shelby starts a wild, new sorority – right next door to Mac (Seth Rogen) and a pregnant Kelly (Rose Byrne).

Desperate to sell their house, the couple beg for Teddy’s help to shut the sorority down. And just like Shelby, Chloe’s not afraid to speak her mind, having weighed in on everything from Taylor Swift’s squad to Kim Kardashian’s naked selfie.

We sat down with Chloe to find out what makes the tough chick tick…

You’re not even 20 yet but you already seem so mature and level-headed…

I still have a lot to learn and a lot of growing up to do. If you’re pursuing a career, it makes you take that responsibility very seriously. I was raised to be confident and speak my mind. I think women can be very forceful in our own way.

Well, you’re certainly not afraid to say what you think – how did you get to be so self-assured?

I don’t know how this happened, but when I turned 17, this huge weight was lifted off my shoulders. I don’t worry about what people say about me. I know who I am [and] who I want to be.

Your character in Bad Neighbours 2 is all about partying – do you get to cut loose and let your hair down IRL, too?

I’ve never been interested in doing heavy partying or rebelling in some way. I’ve been an actress since I was six and I was raised by a very strong and hard-working single mother who taught me good values. I take my work very seriously and I have a lot of fun just being able to travel and work with so many talented people. I don’t need to get crazy to enjoy myself. Also, my mother told me that if I ever got into any trouble she’d ground me!

Your parents split when you were quite young – how did that affect you?

It toughened me up a lot and made me harder on myself. It was as heavy as you can get to dismantle a family, for sure. He just left, so it’s like you have to fend for yourself. When you’re betrayed by someone that is a bloodline, you start to beware of trusting people and to protect yourself at all costs. For a long time, I did that too much. I wasn’t letting people in.

You’re quite a vocal feminist. Was it tough for you being part of a girl gang who dance around in bikinis in Bad Neighbours 2?

No. Seth Rogen is a very smart writer and these sorority girls have a very strong sense of identity. They’re very empowered young women and I think that the film takes a very respectful and positive attitude towards women. We’re actually tougher and wilder than the guys! A lot of wild stuff happens!

Does having fame so young ever get a bit much for you?

It’s not always easy. I’m a pretty upbeat person but obviously you get tired or worried about your work. There’s tremendous pressure in this business and you see how it affects a lot of the people around you. I was once told by someone that the film business is like a boxing match – you get knocked down, but you have to keep getting up and keep fighting!
